86100A/B/C
Firmware Release Notes
embedded clocks from optical and electrical signals up to 16X Fibre Channel.
• Support for 86105D Optical/Electrical Module: The 86105D is a new module supporting 8X
and 16X Fibre Channel as well as 10 Gb Ethernet and 10 G SONET/SDH line rates.
• Improved Clock Recovery Support For SATA: The upper limit for the loop bandwidth
(LBW) has been increased to line rate/250, allowing 6 MHz LBW required for SATA I
signals (1.5 Gb/s). The absolute LBW limit remains at 10 MHz.
• J2 and J9 TJ Measurements: J2 and J9 are new Total Jitter (TJ) measurements from
standards requiring stressed eye analysis for optical and electrical receiver compliance.
• TJ Upper Limit Increased To 10E-1: The upper limit for the BER used in of Total Jitter
(TJ) measurement BER has been increased from 1E-3 to 1E-1.
• I-Q Diagram in Color Grade: The math function ?gVersus?h allows color-graded I-Q
diagrams, a key insight tool to visualize the I/Q signals after demodulation of a complex
optical modulation.
• Remote Skew Control For 86118A-H01: New GP-IB commands now allow remote skew
control for option H01 of the 86118A, a dual remote sampling head with over 70 GHz
electrical bandwidth.
• Additional Trigger Divide Ratio: 1:55 has been added to support more applications using
subrate clocks to trigger the oscilloscope.
• Additional Loop Bandwidth Value: Added 637.5 kHz to "Select from List" for target loop
bandwidth (LBW) of the clock recovery.
• Calibration Timeout Increased to 30 Seconds: During most calibrations the hardware
reacts within a fraction of a second. External programs, such as anti-virus and anti-
spyware software, may keep the CPU busy for seconds. The long timeout ensures
successful calibration in most if not all cases.
General Defects Fixed
• Fixed corner case where too much jitter was reported
• Fixed issue: jitter algorithm related to transition density that resulted in over-reported DJ/
TJ numbers.
• Fixed occasional ghost error message (?gReset PTB?h) when no precision timebase was
installed.
Known Issues
• 86119A (Optical Sampling Oscilloscope) is designed to work on software versions A.03.06
and A.03.05 only.
A.08.00 Release Notes, June 18, 2008 (Differences from Release
A.07.00)
New Feature List
• Support for the new 86108A Precision Waveform Analyzer module. The 86108A is a double
wide module that features two electrical inputs, clock recovery and a precision timebase.
Previously, the combination of these required three separate modules. Now they are
incorporated into a single, double wide module.
• Support for reference receiver options 86116C-025 and 86116C-040. The 86116C has been
replaced with the 86116C-040 and 86116C-025. Option 040 is a direct replacement for the
legacy 86116C as a reference receiver for 39.8 GB/s and 43.0 Gb/s NRZ signals. Option 025
offers reference receiver capability for 17, 25.8 and 27.7 Gb/s NRZ signals which were
previously not available in the 86116C.
• Support for the 86100CU-400 PLL / Jitter Transfer Analysis option.
• Support for the Bulk Optics change on the 83496B Clock Recovery Modules.
• 86108A Setup Wizard to help configure the 86108A module. This wizard has preset
